The Global Ocean is a Ding an sich: a data-based noumenon – or fiction – translated for the human sensorium via instrumentation and software conformation of information. In the GEBCO-WGS’84 (negative) visualisations we catch a glimpse of the inhuman geography of the world; imaginal noesis of ocean-agent perceptrons that inhere this space (umwelt). This transforms into an isometric view of a notional 3D-laser-print crystal structure, as if we can see it from ‘outside.’ A glass sculpture of what we can observe, not of what we can know.

Emerging from this via SSHA and SST visualisations are the mountains and valleys of the sea, the deep circumpolar Antarctic convergence: observed data/derived statistics from remote-sensing spectral information.
